Summary
Small units can achieve high success rates in Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures. The cumulative sum method demonstrates that regular practice allows for consistent, high-quality outcomes in selective cannulation and intervention.
Area of Science:
- Gastroenterology
- Endoscopy
- Medical Quality Improvement
Background:
- Endoscopic Retrograde Cholangiopancreatography (ERCP) is now performed in various healthcare settings, including smaller hospitals.
- Analysis of ERCP performance in a small unit is crucial for understanding workload and success rates.
Purpose of the Study:
- To analyze the success rates of selective cannulation and intervention during ERCP using the cumulative sum method.
- To document the workload and assess performance in a small hospital unit.
Main Methods:
- One endoscopist recorded indications, results, and interventions for all ERCP procedures over 8 years.
- Success rates for selective cannulation and intervention were measured and compared to a 90% target using the cumulative sum method.
Main Results:
- Over 532 ERCPs, 91% selective cannulation and 81% successful interventions were achieved.
- Cumulative sum analysis indicated satisfactory outcomes for cannulation around 100-120 procedures and for interventions around 120 procedures.
- Common findings included normal ERCP (32%), stones (32%), and strictures (15%).
Conclusions:
- The cumulative sum method effectively compares individual performance against targets, ensuring maintained quality.
- Small units can develop and sustain ERCP expertise through regular procedure volume.
